Hi, I’m new to the topic. I’m setting up a 2L SPD. I run into a couple of problems and I need your help to solve it.
I have this Alcatel 2021 vacuum pump, but they do not have any component to connect it to the glass cold trap, I have seen several pieces on the internet, but I do not understand which one is useful for me and why.
I have this vacuum meter, it has cost me 100 dollars, but I read in the forum that it is not the right one, what do you think?
finally buy the equipment to replace the use of dry ice in the cold trap, for this area it is impossible to get dry ice in small quantities, the minimum that is sold is 300 dollars, too expensive for me, so I bought the polysciences p60 It says cool down to -80 but I really doubt it, you suggest that I use it as a coolant in the cold trap, I read several mixtures of alcohol.
I also bought a sous vive de cocina, in your opinion, am I ready to start a round or what other component do I need?
